And now I come to the most remarkable and assuring fact, that, after patient, laborious, and most elaborate scientific comparison, they have come to the conclusion that all the nations of the earth may be grouped into three great families, and have probably descended from three original centres. They name these three great divisions the Aryan, the Semitic, and the Turanian. But we need not trouble ourselves about the names. The classification itself is the matter of supreme importance; for in this discovery of the nineteenth century we find the full confirmation of the account, written by Moses more than 3,000 years ago, of the three sons of Noah surviving the flood more than 4,000 years ago. In that narrative we find the account of mankind starting afresh under three heads, Shem, Ham, and Japheth. Since that time there have elapsed more than 4,000 years, and now, in this nineteenth century, after all the changes that have taken place, we find a body of learned and unprejudiced men, enabled by the discovery of steam to discover amongst mankind, as we now exist, precisely the same threefold division that is described in the Scriptures as having taken place in the days of Noah. Now how are we to explain this fact? What is the cause of this strange coincidence? It is utterly impossible that the Mosaic record should have been constructed in order to suit the scientific discoveries of our own day. And those who honour science would be the last to admit that men of science have constructed their system on the lines of the Mosaic record. But, there is one word that is a key to the whole, one word that is the connecting-link between the fifteenth century _before_ Christ, and the nineteenth century _after_ Him; between the statements of the Scripture and the researches of science, and that one word settles all. That one word is _Truth_, truth in science, and truth in Scripture; truth in the Word, and truth in the works of God. But we have not yet done with history, for the tenth chapter of Genesis gives us some idea of the direction in which these three great families spread themselves over the surface of the globe. A moment’s thought will be sufficient to show that it must be next to impossible to trace these descriptions now. Vast changes have taken place during the 4,000 years that have elapsed. Cities have sprung up and disappeared; whole nations have risen to power, and passed away; names have changed; there have been migrations, invasions, captivities, and dispersions; so that the different families have in many cases been strangely intermingled. But still there is a certain outline given in the Pentateuch, and a certain outline agreed upon by the men of science. Now look at this outline.
